I have a 1990 e30 just picked it up for 500 everything seems to be great accept for when I drive with the heat on sometimes the car will have no power and by the time I hit fourth gear it jerks like the clutch is disengaging itself or its not getting fuel but as soon as I turn the notch for the heat it is instant power ! Any ideas?

I hazzard a guess that the heater motor has been wired by some genious to draw power of the Injector + or coil :(

That's a strange one. Maybe you could find a vacant fuse location and somehow put in a dedicated circuit for the blower.
